【摘要】 (乙烯辛烯)共聚物弹性体(POE)是由美国DOW化学公司使用茂金属催化剂聚合而成的一种聚烯烃橡胶.与传统聚烯烃类橡胶EPDM相比,POE的特点就在于其在聚烯烃塑料基体中分散速度快、分散程度高.为此,我们尝试用马来酸酐接枝的POE(POEgMA)...

【Abstract】 The influences of the maleic anhydride grafting of ethylene\|octene Copolymer elastomer(POE) and the use of modifier (CE\|96) on viscosity,isothermal and nonisothermal crystallization kinetics of nylon 6/POE blends were studied by means of capillary rheometer and differential scanning calorimeter.Compared with nylon 6/ungrafted POE blend, the maleic anhydride grafting of POE decreases the crystallization rate and crystallinity,and increases the crystallization size distribution.The addition of CE\|96 into nylon 6/POEgMA blends further hinders the crystallization rate and crystallinity of nylon 6 due to the chain extending effect of CE\|96 on nylon 6 and the coupling effect at the nylon 6/POEgMA interface.\=
